How Much Mobile Data Do You Need for a USA Trip?

Buying too little data means hunting for Wi-Fi in a parking lot; buying too much means paying for gigabytes you never use. The right size depends less on how long you stay than on how you use your phone. Here is a practical way to estimate it for a trip to the United States.

What uses data — and what barely does

• Maps and navigation: light. Turn-by-turn directions usually use a few megabytes per hour, more in dense cities with lots of rerouting. Offline maps use almost none.
• Uber, Lyft and booking apps: very light — a few megabytes per ride or booking.
• Messaging: text messages are negligible; photos add up to a few hundred kilobytes each and short videos to several megabytes.
• Social media: heavy. Scrolling video-first feeds such as Instagram Reels or TikTok can use several hundred megabytes to over a gigabyte per hour.
• Music streaming: moderate, roughly 40–150 MB per hour depending on quality.
• Video calls: heavy, often 0.5–1.5 GB per hour.
• Video streaming: the heaviest — 1–3 GB per hour in HD.

Daily budgets that work for most travelers

• Light (about 300–500 MB per day): maps, rides, messaging and the occasional search; social media and calls on hotel Wi-Fi.
• Typical (about 1 GB per day): everything above plus regular social media, photo uploads and a short video call now and then.
• Heavy (2 GB or more per day): daily video calls, lots of short-form video, working on the road or streaming music on long drives.

Suggested plan sizes

• Long weekend or short city break: 3–5 GB.
• One week: 5–10 GB for typical use.
• Two weeks: 10–20 GB, or a smaller plan you top up.
• Three weeks or a long road trip: 20 GB or more, or a 24-hour pass style plan if you use a lot of data every day.

Ways to make your data last

• Download offline maps in Google Maps for the cities and parks you will visit.
• Turn off auto-play for videos in social apps, and set photo backups to Wi-Fi only.
• Use hotel and café Wi-Fi for big downloads, app updates and streaming.
• Check what you have left on the My eSIM page; refillable plans can be topped up without installing anything new.

Frequently asked questions

Is 1 GB a day enough in the USA?

For most travelers, yes: 1 GB a day covers maps, rides, messaging and regular social media. Daily video calls or streaming need more.

Can I add more data if I run out?

Yes, on plans marked Top-up. Open My eSIM, log in with your order email and add data to the same eSIM. Otherwise you can buy and install another plan.

Does the plan start when I buy it?

No. The validity period starts when the eSIM first connects to a network in the United States.
